Midnight Black Controller is BDM 20. It is on the mainboard (controller open) or you do the trigger check (visible from the outside, you can google there are pictures how it looks exactly on the BD 10 and 20)

Its a BDM- 010 Controller. The BDM Version is not visible on the outside. You can deduce it from the Model Number thats written on the package and the controller itself. If its CFI-ZCT1W its a BDM-010 Controller. If its CFI-ZCT1W "A" its a BDM-020. So if its a version you dont approve you can look at the package and return it.
